Wiltshire Police are reminding people that using motor vehicles on byways and bridleways is illegal.
The reminder comes after reports of 4x4s and motorbikes being used around Luggershall and Upper Chute.
Police said, "We’ve received reports of motorcyclists and 4x4 vehicles using the byways and bridleways in Ludgershall and Upper Chute.
"The signs in these photos show that you must not drive any motor vehicle where these are displayed.
"We are investigating these reports and would urge motorists to be aware that vehicles are not permitted down these byways.
"Horse riders and pedestrians use these routes – do not place yourself and other users at risk by using these lanes illegally."
